Anthony Olascuaga retained his WBO flyweight world title in controversial fashion, defeating Hiroto Kyoguchi by unanimous decision in a scrappy fight at the Ryogoku Kokugikan Arena in Tokyo. The scores read 117-111, 118-110, 114-113 in favour of the American. But despite an 11th-round knockdown, it was Kyoguchi who arguably landed the bigger, more meaningful punches throughout the fight.
